Abstract

The invention discloses a tensile computer cable, which comprises a cable core formed by the inter-twisting of three insulated wire cores, wherein each insulated wire core comprises a pair of stranded conducting wires at the center of the insulated wire core and paired twisting wrap tapes wrapped on the outer parts of the conducting wires; each conducting wire comprises a conductor and an insulation layer squeezed and wrapped at the outer part of the conductor; a filling rope is arranged at the gap of the cable core; a cabling wrap tape is wrapped at the outer part of the cable core; an inner jacket is squeezed and wrapped at the outer part of the cabling wrap tape; an outer jacket is squeezed and wrapped on the outermost layer of the cable; a double-layered steel-wire armored layer is further weaved between the inner jacket and the outer jacket; and the weaving density is 35%-45%. According to the invention, the outer jacket of the tensile computer cable is a squeezing soft level outer jacket, and outer protective materials can be embedded into the weaved steel-wire layer, that is, the outer jacket has stronger tensile strength and roundness of the cable, so that the phenomenon that the cable is damaged or broken due to the dead weight can be prevented; the double-layered steel-wire armored layer further has the effect of shielding outside signals; and meanwhile, the tensile computer cable has the advantages that the outer jacket can be prevented from cracking and the service life is long.

Description

A kind of tensile type computer cable

Technical field

The present invention relates to the electric wire field, specifically refer to a kind of tensile type computer cable.

Background technology

At present, computer cable is as a class telecommunication cable of transmission signal, for remarkable contribution has been made in the development of Communication in China cause.Along with industrial expansion, the overlay area of signal of communication is more and more wider, and common tensile type armature of cable layer is the pattern that adopts steel wire to twine, and has increased the total weight of cable like this.The communication cable laying of some big specification length is in having the bigger environment of height fall, tend to be damaged even break because of the cable deadweight, particularly rain freeze, the influence of harsh weather such as ice and snow weather, telecommunication cable might cause the signal of communication transmission to be interrupted because freezing, cause the economic loss that can't save.

Summary of the invention

Technical problem to be solved by this invention provides and a kind ofly conducts electricity very well, resistance to tension is strong, oversheath is not easy to crack, the high strength telecommunication cable of long service life.

A kind of tensile type computer cable of the present invention comprises cable core, and its cable core is by stranded the forming of some eradication edge cores; Gap at cable core is provided with gasket for packing, the outer wrapped stranding twining package tape of cable core, and the stranding twining package tape extrudes inner sheath outward, and the cable outermost layer extrudes oversheath, also weaves the double wire armor layer between inner sheath and oversheath.

Further improve, described insulated wire cores is three, and each root constitutes by being positioned at a pair of stranded conductor in its center and being extruded in the outer pair twist twining package tape of stranded conductor.

Further improve, described stranded conductor is by conductor and be extruded in the outer insulating barrier of conductor and constitute.

Further improve, described conductor is the 1st, 2 or 5 class conductors; Described stranding twining package tape, pair twist twining package tape are nonwoven fabric belts.

Further improve, the count of described double wire armor layer is between 35%-45% again.

Beneficial effect of the present invention:

Compared with prior art, the oversheath of cable of the present invention has adopted other oversheath of the soft level of squash type, external protective material can be embedded in the braided steel wire gap, namely has bigger tensile strength, the roundness that has cable again, be damaged or break because of deadweight thereby reduced cable, double-layer wire braiding armouring can also play the effect of shielding outer signals; And has an advantage that prevents oversheath cracking, long service life.

Description of drawings

Fig. 1 is structural representation of the present invention.

Embodiment

As shown in Figure 1, a kind of tensile type computer cable of the present invention comprises cable core, and its cable core thoroughly does away with stranded the forming of edge core by three; Described each thoroughly do away with edge core by being positioned at a pair of stranded conductor in its center and wrapped pair twist twining package tape 3 outside stranded conductor constitutes; Described stranded conductor is by conductor 1 and be extruded in the outer insulating barrier 2 of conductor 1 and constitute.Be provided with gasket for packing 5 in the gap of cable core, the outer wrapped stranding twining package tape 4 of cable core, the stranding twining package tape 4 outer inner sheaths 6 that extrude, the cable outermost layer extrudes oversheath 8, also weave double wire armor layer 7 between inner sheath 6 and oversheath 8, the control of its count is between 35%-45%, and count is difficult for that excessive (count is excessive, protect material outward and can not be embedded in better in the gap between the steel wire, cable does not have better tensile strength).

Conductor 1 described above is the 1st, 2 or 5 class conductors; Described stranding twining package tape 4, pair twist twining package tape 3 are nonwoven fabric belts.

The invention provides a kind of thinking and implementation method of tensile type computer cable; concrete application approach is a lot; the above only is preferred implementation of the present invention; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvement, these improvement also should be considered as protection scope of the present invention.
